On the SPUs, most instructions can operate on registers as if they contained multiple, independent values (thus the single instruction acting on multiple data items).

可能通过在某个寄存器中计算目标地址、并且使用间接跳转指令把控制传给该寄存器中的地址，把跳转指令本身的目标隐藏起来。
The target of the jump instruction itself may be hidden by computing its address in a register and using an indirect jump instruction to transfer control to the address in that register.
最通常的分析是数据依存性分析，它用来确定指令使用的变量(寄存器或内存位置)是否被另一条指令修改。
The most common analysis is data dependence analysis, which is to determine the instructions that use the variable (register or memory location) modified by another instruction.
可程序化量子处理器根据程序寄存器中存储的指令对数据寄存器中的量子态作指定的操作。

iar -指令地址寄存器。
所以该指令会将链接寄存器(存有返回地址)存储到调用函数堆栈框架的恰当位置。
So this instruction stores the link register (which holds the return address) into the proper location in the calling function's stack frame.
几个SPU指令只能处理这些寄存器值中的一个。
It turns out that several SPU instructions deal with only one of the register's values.
在两种模式下，设定64位寄存器的指令将影响所有64位。
In both modes, instructions that set a 64-bit register affect all 64 bits.
其后面是4040处理器(1974发布)，其具有扩展指令集、程序内存、寄存器集和堆栈。
Its successor was the 4040 processor (released in 1974), which had an expanded instruction set, program memory, register set, and stack.
所有指令不管怎样都会对整个寄存器进行操作。
All of the instructions operate on the whole register anyway. The problem before was threefold.
您实际上可以使用基于寄存器的提示指令来实现一些非常高级的提示行为。
You can actually do some fairly advanced hinting behavior using register-based hint instructions.
这就是说，每个寄存器都被分为多个较小的值，指令作用于所有的值上。
This means that each register is divided into multiple, smaller values, and instructions operate on all of the values simultaneously.
很快有了汇编语言，它将1和0抽象成基本的机器指令，例如用值y加载寄存器x。
Quickly came assembly language, which abstracted away the ones and zeros to provide rudimentary machine instructions such as load register X with value y.
你可以设置一些寄存器，并发出一个系统调用指令(或中断)，并由陷阱处理程序直接调用内核代码。
You set some registers and issue a system call instruction (or an interrupt) and have the kernel code called directly from the trap handler.
整个解释器的核心是一个虚拟的寄存器机器，及其支持的一套基本指令集。
The core of the scheme interpreter is the Virtual Register Machine with a set of supported basic instructions.
当这个函数完成时，返回值会通过寄存器3返回，函数本身使用blr指令退出。
When the function is completed, the value is returned through register 3, and the function exits using the BLR instruction.
如果在MSR(机器状态寄存器)中可用的浮点位被禁用，将尝试执行一个浮点指令。
An attempt was made to execute a floating point instruction when the floating point available bit in the MSR (machine status register) was disabled.
length指令确定字符串的长度并将其加载到一个整数寄存器中。
The length instruction determines the length of the string and loads it into an integer register.
可以看到test1()中每次加法都需要读取和存储全局变量errs，而在test2()中，localerrs分配在寄存器上，只需要一条指令。
Note that test1 must load and store the global errs value each time it is incremented, whereas test2 stores localerrs in a register and needs only a single instruction.
大多数指令都遵循类似的格式，结果存储在第一个操作数内指定的寄存器中。
Most instructions follow a similar format, with the register that holds the result specified in the first operand.
brsl代表“branch relative and setlink”，用来分支到函数的入口点并将链接寄存器(LR)设置为返回地址的下一个指令。
BRSL stands for "branch relative and set link." This branches to the function entry point and sets the link register (LR) to the next instruction for the return address.
PPE用载入和存储指令访问主存储器(有效地址空间)，可以在主存储器与内容可以缓存的私有寄存器文件之间移动数据。
The PPE accesses main storage (the effective-address space) with load and store instructions that move data between main storage and a private register file, the contents of which may be cached.
寄存器分配与指令调度是编译器优化过程中的两项重要任务。
Register allocation and instruction scheduling are two important tasks for every optimizing compiler.
LK位指定了下一个顺序指令的地址是否作为子例程调用的返回地址保存在链接寄存器中。
The LK bit specifies whether the address of the next sequential instruction is saved in the Link Register as a return address for a subroutine call.
LK位指定了下一个顺序指令的地址是否作为子例程调用的返回地址保存在链接寄存器中。
The LK bit specifies whether the address of the next sequential instruction is saved in the Link Register as a return address for a subroutine call.
